    I have redmax trimmers, blowers, and stick edgers. Lately during the afternoon when it is real hot the don't want to start or they will start and die. (bog down when trying to use the gas) Is this common for redmax stuff? Or do I need to replace something...:cry: I can't continue running like this it takes to much time. Thanks guys

    i run redmax :weightlifter: , try taking out the spark arrestors on the mufflers. mine actually perfore much better in warm conditions. redmax stuff also takes a minute to warm up before it performs at its best.

    It sounds like a problem many of us have had with the 8000's. Are you running Opti-2 or something similar? I switched to "regular" oil during the summer and it appears to have stopped doing that.

    I have Stihl Equipment and when it's really hot (like everday) it will do the same thing. I clean the Spark Plug and it will start right up and not happen again for awhile. I run the octane and mix per the Manuals, but I also think alot of the places down here sell bogus gas.

    Here in Delaware we have E10 fuel if your state does check your fuel lines, we've seen many failures on all brands. Check carefully it only takes a small crack.

    What model Redmax's are giving you these problems. When did you purchase these machines?
    Last year, many carburator issues surfaced. They would run great while they are cold and even till mid day but after that they would bog and die. The Carbs were set to lean in many instances and were being replaced undewr warranty by my dealer and many other dealers in my area. I would check the obvious stuff first, (fuel line and filter, spark arrestor, How long the trimmer line is if the guard is off the unit). Send me a PM if you want or reply on here with the models and such and I'll tell yea if your models where some my dealer ha trouble with.....

    Burp the gas tanks when it gets hot. By this I mean unscrew the gas cap before starting to let the pressure off the tank. With hot temps, pressure builds up inside the tank and makes it hard for the carb to draw fuel. We have only had this problem with 1 red max blower (we have 3), and this has been only once or twice.

    I have a BCZ2400s that does this but it starts fine, just won't rev to high rpm's. I have removed and checked the muffler, spark plug, and air filter. I believe the dealer replaced the carb shortly after I bought it a couple years ago. The problem just recently resurfaced. My gas tank doesn't appear to be pressured up and mine bogs right from the get go. I'll check the fuel pick up and try some premium gas but it ran fine for a long time on regular gas.

    Could you explain why you believe a pressured up tank would cause this? Just curious. Thanks
